The guiding assembly 3 is used to guide the gas passing through the ventilation opening 10 to flow along the first direction and the second direction respectively.

[0032] For the above-mentioned air duct 1, please refer to Figures 2 to 4, the air duct 1 includes a first side plate 11, a second side plate 12, and a partition plate 13. The partition plate 13 is disposed between the first side plate 11 and the second side plate 12, and the partition plate 13 is perpendicularly connected to both the first side plate 11 and the second side plate 12. The partition plate 13 divides the internal space of the air duct 1 into a first groove 15 and a second groove 16. The openings of the first groove 15 and the second groove 16 both face away from the partition plate 13. The partition plate 13 is further provided with a ventilation opening 10. The ventilation opening 10 penetrates through the partition plate 13, and the ventilation opening 10 communicates the first groove 15 and the second groove 16. On the side of the first side plate 11 close to the first groove 15 and on the side of the second side plate 12 close to the first groove 15, fixing portions 14 are extended. The fixing portions 14 are respectively located on the side of the first side plate 11 away from the partition plate 13 and on the side of the second side plate 12 away from the partition plate 13. The fixing portions 14 are provided with fixing holes 140 for inserting screws to fixedly install the fixing portions 14 on the installation base. The installation base closes the opening of the first groove 15 to form an air duct 150. The air duct 150 penetrates through the air duct 1 along the length direction of the air duct 1, and the ventilation opening 10 communicates with the air duct 150.

[0033] In some embodiments, please refer to Figure 5 , the air duct 1 includes a first pipe body 17 and a second pipe body 18, and the first pipe body 17 and the second pipe body 18 are welded together. The first pipe body 17 includes a first upper side plate 171, a second upper side plate 172, and a bottom plate 173. The first upper side plate 171, the second upper side plate 172, and the bottom plate 173 together enclose the first groove 15. One end of the first upper side plate 171 and one end of the second upper side plate 172 are respectively perpendicularly connected to both sides of the bottom plate 173. The other ends of the first upper side plate 171 and the second upper side plate 172 are respectively extended with fixing portions 14, and the fixing portions 14 both extend in a direction away from the bottom plate 173. The bottom plate 173 is provided with a first ventilation opening 170. The second pipe body 18 includes a first lower side plate 181, a second lower side plate 182, and a top plate 183. The first lower side plate 181, the second lower side plate 182, and the top plate 183 enclose the second groove 16. The top plate 183 is provided with a second ventilation opening 180. One end of the first lower side plate 181 and one end of the second lower side plate 182 are respectively perpendicularly connected to both sides of the top plate 183. The other ends of the first lower side plate 181 and the second lower side plate 182 are respectively extended with connecting portions 184, and the connecting portions 184 both extend in a direction away from the top plate 183. The connecting portions 184 are used to assist in fixing the air duct 1 to the installation base, and the extension length of the connecting portions 184 is greater than or equal to zero. The bottom plate 173 and the top plate 183 are welded and fixed to fixedly connect the first pipe body 17 and the second pipe body 18. The upper surface of the bottom plate 173 constitutes a first surface, and the lower surface of the top plate 183 constitutes a second surface. The first ventilation opening 170 and the second ventilation opening 180 overlap to form a ventilation opening. Along the height direction of the air duct 1, the projection of the bottom plate 173 completely coincides with the projection of the top plate 183, and the projection of the first ventilation opening 170 completely coincides with the projection of the second ventilation opening 180.

[0034] Optionally, the installation matrix is a ceiling or a side wall.

[0035] It can be understood that the air duct 1 can be directly installed on the outer surface of the ceiling or the side wall, or can be installed in an embedded manner. When the air duct 1 is installed in the ceiling or the side wall in an embedded manner, the notch of the first groove 15 is closed by the wall body to form an air duct 150, and the air duct 150 communicates with the ventilation system of the building, and the air flow flows along the length direction of the air duct 1 in the air duct 150. The connecting parts 184 on both sides of the second groove 16 are flush with the outer surface of the wall body, or the surface of the connecting part 184 facing the air duct 150 is connected to the outer surface of the wall body without a gap. Both ends of the second groove 16 along the length direction of the air duct 1 are closed by the wall body to form an air outlet channel, and the air duct 150 communicates with the air outlet channel through the ventilation opening 10. Thus, the air flow can smoothly flow from the air duct 150 and the air outlet channel to the outside in sequence, and can also enter the air duct 150 through the air outlet channel and the ventilation opening in sequence, so as to realize the exchange of the gas in the air duct 150 and the outside gas.

[0036] Compared with the air duct with a circumferentially four-sided closed design, the air duct 1 provided in this application has a double-U shape design, which not only reduces the cost and processing difficulty, but also improves the installation flexibility. Specifically, the upper U-shaped structure of the air duct 1, that is, the first groove 15, uses the wall body to close the notch to form the air duct 150, which saves cost and reduces the processing difficulty compared with the closed air duct. And the lower U-shaped structure of the air duct 1, that is, the second groove 16, is used to install the guiding component 3, provides an outer frame for the guiding component 3, plays a role in fixing and supporting the guiding component 3, and also ensures that the air flow can be effectively guided and distributed when passing through the guiding component 3, and enables the guiding component 3 not to be provided with an additional outer frame, further simplifying the structure. And the extending lengths of the fixing part 14 and the connecting part 184 can be adjusted according to the installation scenario and requirements, enhancing the applicability of the air outlet device 1000.

[0037] For the above-mentioned flow equalizing plate 2, please refer to Figure 5 , the flow equalizing plate 2 is arranged at the bottom of the first groove 15, that is, the flow equalizing plate 2 is arranged on the bottom wall of the air duct 150, and the projection of the flow equalizing plate 2 along the height direction of the air duct 1 covers the ventilation opening 10, ensuring that the gas can be evenly distributed when passing through the ventilation opening 10. The flow equalizing plate 2 is evenly distributed with a plurality of through holes 20, so that the gas flowing into the first groove 15 is effectively dispersed and homogenized by the through holes 20 when passing through the flow equalizing plate 2 for the first time, thereby avoiding the generation of eddy currents or local high-pressure areas at the ventilation opening 10, and improving the air flow stability and efficiency of the air outlet device 1000. At the same time, the flow equalizing plate 2 can also play a certain filtering role, can block large particles or impurities from entering the air outlet device 1000, and protect the components from damage.

[0038] For the above-mentioned guiding component 3, please refer to Figure 6 andFigure 7 , the guiding component 3 includes a first vane component 31, a second vane component 32, a bolt 33, a sleeve 34, an adjusting nut 35 and a fixing nut 36. One end of the bolt 33 is connected to the first side plate 11, and the other end of the bolt 33 is connected to the second side plate 12. The fixing nuts 36 are arranged at both ends of the bolt 33, and the fixing nuts 36 are used to fix the bolt 33 to the first side plate 11 and the second side plate 12. The bolt 33 is used to connect the first vane component 31 and the second vane component 32, and the first vane component 31 and the second vane component 32 are arranged adjacent to each other. The sleeve 34 is sleeved on the bolt 33, and the sleeve 34 is used to separate and fix the first vane component 31 and the second vane component 32. The adjusting nut 35 is arranged on the bolt 33, and the adjusting nut 35 is used to adjust the distance between the first vane component 31 and the side wall of the second groove 16 or adjust the distance between the second vane component 32 and the side wall of the second groove 16. The adjusting nut 35 is also used to adjust the connection tightness between the first vane component 31 and the sleeve 34 or between the second vane component 32 and the sleeve 34.

[0039] In some embodiments, the adjusting member of the guiding component 3 is not limited to the above-mentioned adjusting nut 35, and may also be other structures, such as a knob or a slider.

[0040] It can be understood that in the present application, the vanes are fixed to the air duct 1 through the bolt 33 and the fixing nut 36, and the distance between the vanes and the side wall of the air duct 1 is adjusted through the adjusting nut 35. Compared with fixing the vanes and adjusting the distance between the vanes and the side wall of the air duct through an elastic member, the stability of the vanes is effectively improved, and phenomena such as resonance and uneven deformation of the vanes during the diversion process are avoided.

[0041] Furthermore, the first vane component 31 includes at least one first vane 311, the second vane component 32 includes at least one second vane 321, and the lengths of the first vane 311 and the second vane 321 are equal. The first vane 311 includes a first connecting portion 3111 and a first bending portion 3112, the second vane 321 includes a second connecting portion 3211 and a second bending portion 3212. The first connecting portion 3111 and the second connecting portion 3211 are used for the bolt 33 to pass through. The bending directions of the first bending portion 3112 and the second bending portion 3212 are opposite. The first bending portion 3112 bends towards one side wall of the second groove 16, and the second bending portion 3212 bends towards the other side wall of the second groove 16. The sleeve 34 is arranged between adjacent vanes, and the sleeve 34 is used to separate and fix adjacent first vanes 311, or separate and fix adjacent second vanes 321, or separate and fix adjacent first vanes 311 and second vanes 321.

[0042] It can be understood that the first direction is the bending direction of the first bending portion 3112, and the second direction is the bending direction of the second bending portion 3212. The first direction and the second direction are arranged in mirror symmetry, axial symmetry or asymmetry. By providing blades with two different bending directions, the guiding assembly 3 can effectively guide the gas passing through the ventilation opening 10 to flow along the first direction and the second direction respectively. Specifically, when the gas enters the second groove 16 from the first groove 15 through the ventilation opening 10, the first bending portion 3112 of the first blade 311 will guide part of the gas to one side wall of the second groove 16, causing it to flow along the first direction. At the same time, the second bending portion 3212 of the second blade 321 will guide another part of the gas to the other side wall of the second groove 16, causing it to flow along the second direction. In the above manner, the gas is effectively dispersed and guided in the second groove 16, achieving uniform distribution and directional flow of the air flow, and improving the air flow control effect and usage efficiency of the air outlet device 1000.

[0043] In some embodiments, the first blade assembly 31 and the second blade assembly 32 are symmetrically arranged, the number of the first blades 311 and the second blades 321 is equal, and the lengths of the sleeves 34 for separating and fixing the first blades 311 and the sleeves 34 for separating and fixing the second blades 321 are equal. The symmetrical design of the blades is beneficial to the uniform distribution and directional flow of the gas in the second groove 16, further improving the air flow control effect and usage efficiency of the air outlet device 1000.

[0044] In some embodiments, the first blade assembly 31 and the second blade assembly 32 are asymmetrically arranged, and the lengths of the sleeves 34 between any adjacent blades are not exactly the same. The asymmetric design of the blades increases the flexibility of the guiding assembly 3 and can achieve more complex and precise air flow control effects. Specifically, by adjusting the lengths of the sleeves 34 at different positions or changing the number of the first blades 311 and the second blades 321, the flow direction and speed of the gas can be further adjusted to adapt to different usage scenarios and air flow requirements.

[0045] It should be noted that the extending ends of the first bending portion 3112 and the second bending portion 3212 do not protrude from the air duct 1, ensuring the smooth and beautiful appearance of the air outlet device 1000 while effectively preventing collisions or damages caused by the protruding ends of the blades, and improving the safety and durability of the air outlet device 1000.

[0046] In some embodiments, both the first blade 311 and the second blade 321 are made of aluminum alloy.

[0047] In some embodiments, please refer to Figure 8, the air outlet device 1000 further includes a connecting member 4. The number of air ducts 1 is at least two. The connecting member 4 is used for fixedly connecting any two adjacent air ducts 1. Connecting holes 19 are provided at both ends of the first side plate 11 and the second side plate 12 of the air duct 1. The connecting holes 19 are used to cooperate with the connecting member 4 to limit and fix the adjacent air ducts 1, effectively preventing the misalignment of the splicing of the air ducts 1 and improving the stability of the splicing and the appearance aesthetics of the air outlet device 1000.

[0048] In some embodiments, the length of the first blade 311 and the length of the second blade 321 are both equal to the length of all the air ducts 1. By configuring blades with a length matching the length of the entire air outlet device 1000 instead of splicing multiple shorter blades, the air outlet device 1000 is more uniform in air flow guiding and dispersion, reducing the air flow disorder or resistance that may be generated due to blade splicing.

[0049] In some embodiments, the length of each air duct 1 is less than or equal to 3000 mm.

[0050] In some embodiments, after the air duct 1 is fixed by the connecting member 4 and welded and fixed to the flow equalizing plate 2, the air duct 1 can also be subjected to a spraying treatment. The spraying treatment can not only enhance the aesthetics of the air outlet device 1000, making it more in line with various indoor decoration styles, but also provide an additional protective layer to prevent the air duct 1 from corroding or aging due to long-term exposure to the air.

[0051] In the embodiment of the present utility model, the air outlet device 1000 includes an air duct 1, a flow equalizing plate 2, and a guiding assembly 3. The air duct 1 is provided with a ventilation opening 10. The flow equalizing plate 2 and the guiding assembly 3 are both arranged in the air duct 1. The flow equalizing plate 2 is used for evenly dividing the gas passing through the ventilation opening 10, and the guiding assembly 3 is used for guiding the gas passing through the ventilation opening 10 to flow along the first direction and the second direction respectively. The air outlet device 1000 realizes bidirectional air flow output through the guiding assembly 3, effectively improving the uniformity of the indoor air flow distribution.

[0052] The present utility model provides an embodiment of an air conditioning system. The air conditioning system includes the above-mentioned air outlet device 1000. For the structure and function of the air outlet device 1000, reference can be made to the above embodiments, and details will not be repeated here.
